Tach to Alt connection?

Does this alternator have a place to connect a tach to it? I'm wondering if I can connect to the extra spot where the warning light attaches(yellow), or where the cable to the battery attaches (red)
Thanks

No, none of those spots. If it has one, it will be labeled "W".

If you do not have one, you need to tap into the raw AC feed before the rectifier. Hard to see if something is accessible in your picture. Take some better pictures and I can let you know where to connect.

The rectifier is the Brass square looking thing right?

its out of the old engine, the 2.5 gas. the one I got with the 200 was a bit beatup looking and this was brand new and it fit.

I have been looking for something else that will fit. The stock alt is only 45 amps

No, AFAIK the brass thing is the noise suppressor.

The rectifier is built into the three plates below the red arrows.

From what I can see the heavy wires coming from below with the white fabric insulation should be the raw feed from the alternator. Any of those should supply a tach signal.

The Defenfer 200TDI alternators come in 45 and 65 amp versions.
